Preterm newborn, gestational age 35 completed weeks

This code identifies a liveborn infant delivered prematurely at exactly 35 completed weeks of gestation. It signifies a late preterm infant, indicating a higher risk for certain neonatal morbidities compared to full-term infants, but generally better outcomes than earlier preterm births.

Apply this code when documentation explicitly states a gestational age of 35 completed weeks at birth for a liveborn infant. This is typically supported by obstetric records, ultrasound findings, and pediatric assessment of gestational age. It is used in conjunction with other codes describing the newborn's condition.

• Do not use for infants born at 35 weeks and 1 day or more; use the appropriate code for 36 completed weeks.
• Always sequence this code after the Z38.- liveborn infant code.
• Ensure the documentation clearly specifies "completed weeks" to avoid miscoding based on incomplete week counts.
